To all 'whom t may concern:

Be .itknown that I, ISRAEL J. MARTIN,

Pittsburgh, in the county of Allegheny and StateV of Pennsylvania, have invented certain new and useful Improvements in De- Yvices for Cleaning-Windows, of which the following is a speciication.

An object of my invention is to provide a new and improved window cleaning device comprising a movable squeegee or cleaning member located on the Youtside of the sash or Window-pane, and means operable from the inside of the sash or window-pane for moving the squeegee over the windowpane.

While my invention may be employed for cleaning windows located in various structures, it is especially applicable for use in keeping clean the window or windows through which the driver of a moving vehicle looks while running t-he vehicle, such for eX- ample, as the window on the platform of a street car, an engineers cab, or the front window of an automobile.

By the use of my invention, a window of the character mentioned may be kept free of moisture, sleet, snow, etc., while the car, etc. is running.

1n the accompanying drawings, which illustrate applications of my invention, Figure 1 is a rear .elevational view of a window sash and window-pane embodying my invention; Fig. 2, a front view of the same; Fig. 3, a horizontal sectional view taken on line Ill-Hl of Fig. 1; Fig. 4, a vertical sectional view taken on line lV-V of Fig. 1; Fig. 5, a similar view taken on line V--V of Fig. l; Fig. 6, a broken rear elevational view showing a modified form of closure means; Fig. 7 a sectional view of the same taken on line VIL-V11 of Fig. 6; Fig. 8, a view similar to Fig. 6 showing a still further modified form of closure means; and Fig. 9, a horizontal sectional view taken on line lX-llX of Fig. 8. Referring to the drawings, ldesignates a window-pane, and 2 the sash therefor. rllhe side members 3 of the sash are each provided with a vertically extending slit 4, and, as illustrated, with vertically extending wear-strips 5, the latter being secured to the side members of the window sash by means of screws 6.

The cleaning apparatus, as illustrated and as preferred, comprises a vertically ymovable squeegee 7 disposed `on `its S0011 SLS the eneide of the'sash and window-pane. The flexible portion a of the squeegee is designed to extend substantially throughout the width of the window-pane, and the member b of the squeegee 1s extended beyond the windowpanel with the respect-ive ends thereof mounted in an outwardly projecting portion 8 of a squeegee carrying member 9, which` latter is arranged on the inner side of the sash.

As shown, I employ two members 9 one varranged on the inner side of each of the side members 3 ofthe window sashl with the outwardly extending portions 8 of the said members 9 projecting through the slits 4 formed in the side members of the sash.

The operable means for moving the squeegee over the window-pane comprise as illustrated, a spring controlled roller or hollow rod 11 having its spring 12 located therein. The said roller 11 is similar to the well known spring controlled curtain roller, and is mounted on brackets 13 located at the upper ends of the respective side members 3.

Extending transversely of the interior of the sash, I provide two rods 14 and 15. Said rods are adapted to carry the respective members 9. 'llhe upper rod 14 is connected with the spring controlled roller 11 by means of flexible bands 16.

rlhe cleaning device is designed to be operated by exerting a downward pressure or pull on the lower rod 15, which pressure acts vagainst the tension of the spring 12, and the downward movement given to rod 15 carries the squeegee down over the outside' of the window-pane, thus removing the moisture, etc., that has accumulated on the pane. Due to the action of the spring 12, the downward pull or pressure is released, the said rods carrying the squeegee will be carried upwardly, as will be readily understood.

17 designates a casing secured to the brackets 13 and designed to cover the spring controlled roller, etc.

For the purpose of closing the slits to pre vent the entrance of air when the apparatus is not in use, ll have shown several forms of closure means. In the form of Fig. 1, ll provide two flexible bands 18 having their upper ends secured to the lower rod 15 and movable therewith, and their lower ends iiXed to the lower portion of the side members 3.

In the form of Fig. 6, the closure means comprise hinged strips 19 respectively secured to the inner faces of the side members of the sash. In this form, itis necessary to swing the strips on their hinges 20 away from the slits in the sidev members before pulling down the cleaning device.

In the form of Fig. 8, the closure means comprise horizontally movable strips 2l disposed within vertically extending members 22, which latter are secured to the inner faces of the side members.

What I claim is A window cleaning device comprising a cleanin member, a frame located on the inner side of the sash and including two brackets arranged to slide on the inner side of the sash with each bracket having a portion projecting through a, slot 1n the sash,

an upper and a lower cross. rod each having 2o its ends secured to the brackets, said cleaning member carried by the projecting pon.

tions of the brackets, a spring controlled roller disposed on the inner side of the sash,

land a iexible band connecting the spring 25 ISRAEL J. MARTIN.
